>=app-admin/rsyslog-8.19.0 builds against dev-libs/libfastjson instead of
dev-libs/json-c like
previous versions. To avoid runtime errors when mixing with depedencies
which were build
against dev-libs/json-c we are now enforcing >=dev-libs/liblognorm-2.0.1
(first liblognorm
version in repository which requires dev-libs/libfastjson) dependency.
